"did I had an extremely expensive wife - she would see a new car that she liked and just buy it... under California law I was bound to buy her debts. I think I turned out 16 novels in five years."
- Philip K. Dick

Eyes are hovering, sem-autonomous surveillance drones with cameras to send images (and guns to respond if need be). An entire system of a hundred or more drones could be remotely controlled from a central location under an auto-scan program.

I sent an eye scurrying off toward Saint Stephen's at full speed, which meant a wait of about twenty minutes until it topped the range. Another, I sent straight up, skywards, which meant perhaps ten minutes for a long shot of the same scene. Then I put the auto-scan in full charge of operations and went downstairs for a cup of coffee.
